    Single-molecule view of coordination in a multi-functional DNA polymerase

    Raymond F Pauszek III, Rajan Lamichhane ... David P Millar
    The primer extension and 5' flap processing activities of DNA polymerase I are physically coordinated by combined movements of the DNA substrate and the 5' nuclease domain of the enzyme.

    Reformulation of an extant ATPase active site to mimic ancestral GTPase activity reveals a nucleotide base requirement for function

    Taylor B Updegrove, Jailynn Harke ... Kumaran S Ramamurthi
    Reengineering the nucleotide-binding pocket of an extant ATPase to restore ancestral GTPase activity revealed an ATP-dependent intermediate required for function and suggested why the protein evolved to use ATP.

    Decoding the physical principles of two-component biomolecular phase separation

    Yaojun Zhang, Bin Xu ... Ned S Wingreen
    Phase separation of two-component multivalent systems is suppressed at rational polymer stoichiometries, suggesting possible cellular strategies for regulating the formation and function of biomolecular condensates.

    Anti-ferroptotic mechanism of IL4i1-mediated amino acid metabolism

    Leonie Zeitler, Alessandra Fiore ... Peter J Murray
    IL4i1 is an amino acid oxidase expressed in the mammalian immune system and snake venoms, which control diametrically opposite cell protection versus cell death pathways, respectively.

    Endoglycan plays a role in axon guidance by modulating cell adhesion

    Thomas Baeriswyl, Alexandre Dumoulin ... Esther T Stoeckli
    Endoglycan fine-tunes the interaction between guidance molecules and surface receptors during axon guidance and cell migration.

    Functional specialization within the inferior parietal lobes across cognitive domains

    Ole Numssen, Danilo Bzdok, Gesa Hartwigsen
    Data-driven and effective connectivity analyses reveal patterns of functional specialization, common mechanisms, and brain-wide interaction profiles within the human inferior parietal lobes for multiple functional domains.

    Cystic proliferation of germline stem cells is necessary to reproductive success and normal mating behavior in medaka

    Luisa F Arias Padilla, Diana C Castañeda-Cortés ... Juan I Fernandino
    In medaka fish, the reduction of cystic proliferation of germ stem cells declines gametogenesis, reproduction success, and male sexual behavior, with a decrease of mating vigor.

    Theory for the optimal detection of time-varying signals in cellular sensing systems

    Giulia Malaguti, Pieter Rein ten Wolde
    A theory is presented for the optimal design of cellular sensing systems that maximizes the sensing precision given resource constraints.

    TDP-43 maximizes nerve conduction velocity by repressing a cryptic exon for paranodal junction assembly in Schwann cells

    Kae-Jiun Chang, Ira Agrawal ... Jonah R Chan
    Glial TDP-43 regulates splicing and expression of neurofascin and is required for proper assembly and maintenance of paranodal axoglial junctions.

    Tonic firing mode of midbrain dopamine neurons continuously tracks reward values changing moment-by-moment

    Yawei Wang, Osamu Toyoshima ... Masayuki Matsumoto
    Although the phasic activity of midbrain dopamine neurons is known to represent reward values, these neurons displayed a tonic firing mode to continuously track reward values changing moment-by-moment.
